Leaks!!!!

[Mrmacdude]

its a 68 automag.
It leaks!!!! when i screw in the air, it leaks through the barrel. when i shoot it leaks through the barrel, then it stops until the trigger is jostled!!! what to do?????????

[Dayspring]

Check the orings on the powertube tip as well as inside the powertube. If that doesn't solve it, there's a chance your powertube spacer is wrong and is causing the leak.

sounds like you need to replace the powertube O ring. probably worn out...

[Mrmacdude]

is the power tube o-ring a floppy blue disc???

[Dayspring]

No. The powertube oring is INSIDE the long slender tube after you take the bolt off.

[cgrieves]

Take the valve out of the body, take the bolt off the front of the valve and unscrew the brass tip. In a classic (non level 10) configuration a spring or spacer should come out first, then underneath will be your power tube O ring (or not as the case may be!)

The blue disc is a bumper to stop the bolt hitting the body.

it could also be the on/off assembly inside the valve but it also could be a simple o ring.

o-ring was fine, replaced it anyway. There was a peace of shell inside the grip frame, where the trigger trips the sear or whateveer.
